Something I missed in the off-list review for this PR: I think this
commit message is a bit heavy on the advice part, rather than on the
real advantage the --skip flag brings, which is that it's less
cumbersome for the user to skip a commit, and brings consistency to
the commands. Maybe something like:
git am or rebase have a --skip flag to skip the current commit if
the user wishes to do so. During a cherry-pick or revert a user
could likewise skip a commit, but needs to use 'git reset' (or in
the case of conflicts 'git reset --merge'), followed by 'git
(cherry-pick | revert) --continue' to skip the commit. This is
more annoying and sometimes confusing on the users part. Add a
`--skip` option to make skipping commits easier for the user and
to make the commands more consistent.

I see that in some cases (e.g 'rollback_single_pick'), we just check
if either REVERT_HEAD or CHERRY_PICK_HEAD exist, but would allow the
"wrong" command to be used, e.g. 'git revert --abort' when a
cherry-pick is in progress. This helps avoiding that, good!

We don't support rebase in 'sequencer_skip' yet, makes sense as this
patch is focused on cherry-pick and revert. There's nothing
preventing supporting that in the future though.

If there's no sequencer directory, we don't need to continue the
cherry-pick/revert, as there's nothing left to do. Otherwise we
continue. Good.
So this looks good to me.
